It is a known fact that the fundamental component of  our daily life is energy. Energy resources are essential for any society, be it one dependent on subsistence farming or an industrialised country. There are many different sources of energy, some well-known such as coal or petroleum, others less so, such as tides or the heat inside the Earth.

Energy resources is different from types of energy. Energy resource is the way of getting energy.

Types of sources available for electric energy

Generally energy resources are available in nature. They are

  • Renewable resources

  • Non renewable  resources

  • Inexhaustible energy resources



Renewable Energy Sources

  • Renewable  resources are infinite source in nature.

  • Renewable  resources are not likely to run out.

  • Renewable  resources can begin again.

  • Some of  the examples of  Renewable energy resources are,

    • Solar energy
    • Wind energy
    • Hydro energy
    • Bio fuel


Non Renewable Energy Sources

  • Non Renewable resources are the finite sources that occur in nature.

  • It does not renew itself

  • As time passes on, non renewable  resources gets depleted.

  • Some of  the examples of  Non Renewable resources are,

    • Coal
    • Oil
    • Fossil fuels


Inexhaustible energy resources

Inexhaustible energy resources are resources that are constantly produced.



  • The resource from the sun in the form of radiations is the solar energy. Sun is a source of enormous energy.

  • It is believed that with just 0.1 per cent of the 75,000 trillion KWH of solar energy resource that reaches the earth, the planet’s energy requirements can be fulfilled.



  • It is the resource produced from biological systems.

  • Bio-energy resource is produced either by direct use of  biomass or its conversion into gaseous or liquid fuels and includes biogas.



  • Wind has kinetic energy by virtue of the movement of large masses of air caused by differential heating of the atmosphere by the sun.

  • This resource can be utilised for performing mechanical and electrical works.

  • Wind turbines can be used to generate electricity, for lifting water from wells and for direct water pumping.



  • Geothermal energy is the energy resource produced by natural processes occurring within the earth.

  • The major source of this energy (in the form of heat) is molten underground rock or magma.

  • Geothermal energy is extracted for heating and power generation from natural steam, hot water or dry rocks in the Earth’s crust.


Points to Remember

  • Electric energy cannot be created not destroyed.

  • Electric energy can transform form one form to another form of energy.

  • Hence primary energy resources are needed to produce electric energy.

  • Two types of energy sources, renewable and non renewable energy resource.

  • Since non renewable energy resources are depleting , future electric energy needs can be satistified by renewable energy resources.
